Product Introduction: It is a high-performance electro-hydraulic servo valve under Moog’s product line. It integrates advanced electro-hydraulic conversion technology and precise control mechanisms. It can accurately convert electrical signals into hydraulic energy output, and is an important part of high-precision electro-hydraulic servo systems.
Technical Specifications: The maximum working pressure is 35.0 MPa. The flow range is 3.8 – 100 l/min when the valve pressure drop is 7.0 MPa. The resolution is less than 0.1%, and the hysteresis is less than 0.2%. The frequency response is 40 – 60 Hz (with ±100% input signal).
Functional Features: It adopts a direct-acting design, which avoids the leakage loss of the pilot stage, and its dynamic response is independent of the supply pressure, while greatly improving the anti-pollution ability of the valve. The spool position is detected by a displacement sensor, and the built-in electronic amplifier performs closed-loop control on the spool position, ensuring high control precision. It has the advantages of energy saving, no pollution, strong environmental adaptability, low operating noise, and durability without frequent maintenance.
Application Scenarios: It is suitable for electro-hydraulic servo systems in various industrial fields, such as the position control systems of machine tools, the speed control systems of rolling mills, and the force control systems of forging equipment. It is also used in the electro-hydraulic servo systems of aerospace and aviation fields, such as the attitude control systems of satellites and the landing gear control systems of aircraft.
